10.2.5 TX VGC Calibration
The Tx VGC calibration is to calibrate the Tx linearization over a reference frequency.
Tx VGC calibration is to control the Tx power (dBm) with accuracy in the antenna in portion to the linear
growth of the Tx VGC value.
10.2.6 TX Reference Calibration
The TX REF calibration is to calibrate the tx power compensation vs frequency , which is based on the
measured power on a reference power .
Whenever frequency is changed, the reference calibration data after the tx ref calibration is to compensate the
tx power (dBm) on a frequency.
10.2.7 RX LNA Offset Calibration
LGE's UE(L2000) have multiple LNA step. So The RX LNA OFFSET calibration is to calibrate RX transition gain
value at each LNA step .
The RX LNA Calibration is to control the RX Gain and LNA step with accuracy in the rx0/rx1 path in portion to
the linear growth of the RX power.
